Perhaps your user name says it all. You are not ready for a mature relationship. That's okay but until you are I would refrain from having "boyfriends" and just date around. Once ready for a mature relationship then you will want love and hugging.
It seems that everyone is questioning her how she could think it is weird. The thing that the majority of you are forgetting is that YOU DO NOT KNOW her situation. She has supplied us with limited information which makes it impossible to provide judgments on. The fact that she had to ask this questions leans towards her feelings uncomfortable. Now my advice is to talk to him about it. If you feel like he is crowding you then ask him to tone it tone a bit. Do it in a mature way so he doesn't feel like you are pushing him away. Hugs themselves aren't bad, but overdoing anything usually is.
I can understand what you are asking because it would really bug me to have someone trying to give me hugs all the time when hugs are the last thing on my mind! I might just rudely 'scrape him off.' Don't get me wrong. I LOVE a good hug. But I don't want to feel SMOTHERED, which is what I think you are trying to describe. Maybe you could explain to him that he is coming on a little too strong for you, that you like him but you want the hugs to feel more 'special.' Sometimes less is more! Think he can understand that? Hope so.
